Disney’s $1 Billion Bet on a Magical Wristband | WIRED

Their MagicBands, tech-studded wristbands available to every visitor to the Magic Kingdom, feature a long-range radio that can transmit more than 40 feet in every direction. The hostess, on her modified iPhone, received a signal when the family was just a few paces away. Tanner family inbound! The kitchen also queued up: Two French onion soups, two roast beef sandwiches! When they sat down, a radio receiver in the table picked up the signals from their MagicBands and triangulated their location using another receiver in the ceiling. The server—as in waitperson, not computer array—knew what they ordered before they even approached the restaurant and knew where they were sitting.
